A perculator (?perc? for short) is basically an additional water chamber found in the main shaft of the bong tube. Several companies use different designs, but they all focus on more water to smoke interaction, making for a better filtered and cooler hit. Some of the better known companies take it a step farther by adding diffusers into their percs, which basically break the smoke up into smaller bubbles making a cooler smoke.

Here is an example of a 3-chambered Phx trinity.




What is a diffuser?
A diffuser is another type of downstem for a bong. Contrary to a downstem, a diffuser resembles a test tube as its sealed on the end or pierced with many small holes or slits. These slits break up the smoke into smaller bubbles than a normal downstem.

Why the need for smaller bubbles? The smaller the bubbles, the greater the surface area of the smoke that contacts the water, thus filtering and cooling the smoke more efficiently. This makes the bong almost silent silent. Many glass companies sell diffusers to fit their bong: Roor, Phx, and Bluedot.

Here is a pic of a german Roor diffuser along next to a Phx diffuser.

nice, i was reading some posts at toke-n-talk and when they mentioned percs i went to google images to see what it was.. this must be the best marijuana forum ever, cause that img i clicked directed me back to RIU! and this thread is from 2007!! sorry for resurrecting it though..

water filters thc out of smoke.
more than one perc is just being wasteful.

yea but luckily its not very soluble..
THC Solubility: 2.8 g/l (water, 23 °C)

oh, so we are only wasting a little of our medicine that we payed money for, so it's no big deal..?

btw, nice wikipedia fact..

So don't use peculator, or a diffuser for that matter since it increases the interaction with water. I personally want to try one.

why does everyone have to nit pick and be dicks when someone is just trying to put some useful info out there. I thought the post was informative to people who don't know what a perc or diffuser is and what they're purpose is
